A solution contains 0.5 moles of MgSO4 dissolved in 0.6 liters of water. In water MgSO4 dissociates into one Mg2 particle and on
mr_godi [17]

Answer:

1.7 Osm/L  

Explanation:

Osmotic concentration is the number of osmoles (Osm) of solute per litre of solution .

\text{Osmotic concentration} =  \dfrac{\text{No. of osmoles }}{\text{Litres of solution}}

An osmole is the number of moles of solute that contribute to the osmotic pressure of a solution.

1 Osm = i × n, where

i = the van't Hoff i factor and

n = the number of moles

The van't Hoff i factor is the number of solute particles obtained from 1 mol of solute.

For example,  

MgSO₄(aq) ⟶ Mg²⁺(aq) + SO₄²⁻(aq)

1 mol of MgSO₄ produces 2 mol of ions in solution, so i = 2.

\text{Osmotic concentration} = \dfrac{\text{1.0 Osm}}{\text{0.6 L}} = \textbf{1.7 Osmol/L}

At 25 °C, only 0.0990 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 °C? AB3(s)↽−−
maksim [4K]

Answer:

Ksp=2.59x10^{-3}

Explanation:

Hello,

In this case, given the 0.0990 moles of the salt are soluble in 1.00 L of water only, we can infer that the molar solubility is 0.099 M. Next, since the dissociation of the salt is:

AB_3\rightleftharpoons A^{3+}+3B^-

The concentrations of the A and B ions in the solution are:

[A]=0.099 \frac{molAB_3}{L}*\frac{1molA}{1molAB_3}  =0.0099M

[B]=0.099 \frac{molAB_3}{L}*\frac{3molB}{1molAB_3}  =0.000.297M

Then, as the solubility product is defined as:

Ksp=[A][B]^3

Due to the given dissociation, it turns out:

Ksp=[0.099M][0.297M]^3\\\\Ksp=2.59x10^{-3}

Regards.

Using your knowledge of reactions and mechanisms, draw the mechanism for the formation of 2-methylpropene from 2-methyl-2-propan
BARSIC [14]

Answer:

Here's what I get  

Explanation:

The reaction is an E1 elimination of an alcohol to form an alkene. It has three steps:

1. Protonation

The alcohol is protonated with aqueous sulfuric acid to convert it into a better leaving group.

2. Loss of the leaving group

A water molecule leaves in a unimolecular process to form a stable 3° carbocation.

3. Loss of an α-hydrogen

A water molecule removes an α-hydrogen, forming 2-methylpropene and regenerating the original hydronium ion.
